1. Riya scored x marks in Mathematics, y marks in English and z marks in General Science. The sum of her marks in English and General Science is 18 more than in Mathematics. Express his information algebraically.
2. A man had 260 watches. He sells x watches every day. Write an Algebraic expression to show that number of watches he would be left after t weeks.
Dear Student,
Please find below the solution to the asked query:
1 ) Given : Riya scored x marks in Mathematics, y marks in English and z marks in General Science.
So , The sum of her marks in English and General Science = y + z
Also given : The sum of her marks in English and General Science is 18 more than in Mathematics. So
y + z = x + 18 ,
y + z - x = 18 ( Ans )
2 ) A man had 260 watches. He sells x watches every day.
And after t weeks ( 7t days , We know 1 week = 7 days ) total number of watches sold = x ( 7t ) = 7 xt
Therefore,
After ' t ' weeks , total number of watches he would be left = 260 - 7 xt ( Ans )
